Here is a photo of the saddle. I realize that you can't tell much from a saddle, but this is it. My aunt is going to see how short the stirrups will go, and if you can add holes to make them shorter. She is meeting us at the next riding lesson to have the instructor/horse owner look at the saddle and see if it will work for my daughter. While I'm learning as much as I can, it is ultimately her recommendation I will follow.
I'm still trying to figure out if this was my aunts, grandpas or my dad's saddle. If it's my dad's or grandpa's I want it, even if it's not going to work for her. If it's my dad's it's at least 40 years old! If it's 40 years old, it's in dang good shape.
Since she's on school horses, I would advise against buying a saddle for her. Instead, buy her a nice saddle pad or blanket with matching horse boots. That way she'll have something to use on the lesson horses that is personal and she won't grow out of it .
